The method of steepest descents has been used to evaluate solutions for the potential of a vertical electric dipole over an interface, wherein the characteristics of both media have been expressed in generalized (nonmagnetic) terms. The nature of the propagation is found to depend upon the relative loss tangents of the two media, and to consist of spherical waves and (in the more lossy region) two additional waves with surface bound properties, independently of the location of the dipole.
